An Experimental Study on the Corrosion Behavior in the Steel Meterial Embedded in Cement Mortar with Metal Spray Method

금속용사피막을 갖는 강재의 시멘트 모르타르 내 부식거동에 관한 실험적연구

The metal spray method, one of the surface anti-corrosion methods to prevent the corrosion of the steel material, does little effects on the material, while it can be used on a wider surface. However, metal spraying is used only in a limited environment, and research on the case of using with concrete is lacking. The purpose of this study was to observe the corrosion behavior of steels with metal spray coatings in concrete using electrochemical methods And to evaluate the performance of the method according to the type of metal used in the metal spray. As a result, the Al metal spray coating showed the best performance, because Aluminum is oxidized in the cement mortar and forms alumina oxide film.
